STEAM-BOILER.

SPECIFICATION forming part of Letters 'Patent No. 658,096, dated4september is, ieoo; Application led December 22. 1899. :Serial N0-741219- (N0 model- To all whom it may concern:

Be it known that'LIsHAM SEDGWICK, a citizen ofthe United States,residing at Richmond, in the county of Wayne and State of Indiana, haveinvented new and useful Im.

provements in Steam-Boilers, of which the following is a specification.

My invention relates to improvements in steam-boilers in which a largesteam capacity is attained in a comparative small space; and the objectsof my improvements are, iirst, to provide a steam-boiler that will beeasy of construction and one that can be readily and easily repaired;second, to provide a boiler having duplicate parts, by which thecapacity can be increased or diminished at will; third, to provide aboiler with great heating capacity witha comparative small amount ofmaterial andto occupy a small amount of space; fourth, to provide aboiler that will hold a small amount of Water to steam quickly and to belight, strong, and safe; fifth, to provide a newarticle of manufacturein a steam-boiler that can be made and sold at a comparative small costand at the same time capable of developing a great amount of steamquickly, and, sixth, to provide a boiler that will produce dry steamwith perfect circulation and be especially adapted for use on vehicles.A

I attain these objects by the combination and arrangement of partsillustrated in the accompanying drawings, in which- Figure l is aperspective inside View of the rear section. Fig. 2 is aperspectiveoutside View of the front section of my boiler. Fig. 3 is asectional elevation of the front, rear, and an intermediate section,taken on the line XX of Figs. l and 2; andFig. 4 is an outside view ofthe front, rear, and an intermediate section.

Similar letters of reference refer to similar parts throughout theseveral views.

My boiler is composed of two or more sections, each complete in itselfand with complete circulationin itself, joined together and connected bypipes leading from one section to the other, so as to form a boiler ofany capacity desired.

An exit-flue A is provided in either the rear or front section, or itmay be between the sections, but I prefer to place it in the rearsection, as shown in the drawings, and the front section is providedwith afuel-doorB.' Otherwise thetwo outside sections are duplicates ofeach other. With this in mind it will be seen that Fig. l is an'insideview, and Fig. 2 an outside View, of the outside or end sections.`

The rear wall C and the front wall O and 6o the water-legs D are made oftwo thicknesses of material, with space between for Water and steam,tied together at frequent inter- -vals by stays of metal extending fromone plate to the other, thus tying the plates to prevent them fromspreading apart.

Each section is provided with two or more sets of water-tubes E, placedat an incline opposite to each other, the ends of said watertubes beingsecured in the inner plate of the 7o water-legs D, thus making aconnection between the water-legs D by means of said water-tubes E.Opposite the end of each watertube, in the outside plate of thewater-legs, openings with plugs G are provided, the object of which isto afford means for cleaning the inside of the water-tubes and inreplacing or removing the water-tubes.

F F F" F represent openings into the steam-receptacle and the water-legsof each 8o section, as shown in Fig. l. Corresponding openings are alsoin the rear of the front section, Fig. 2. These openings are adapted toreceive nipple-pipes, one end of the nipple to be secured in theopenings F on the rear sec- 8 5 tion and the other end of the nipple tobe secured in a corresponding opening in the front section, thus unitingthe two sections and by this providing for circulation between thesections. 9o

Caps or {ianges N and N are provided to cover the space between thesections, as shown in Figs. 3 and 4t. Should it be desired to increasethe size and capacity of the boiler, then in that case intermediatesections without front or back walls can be put in between the front andrear sections, as shown in Fig. 3. The intermediate sections haveneither a back nor front plate or wall, as do the front and rearsections; but they have water-legs and steamroo space to correspond withthe water-legs and the steam-space on the front and rear sections. Theyare also provided with two or more sets of water-tubes placed at anincline to each other. I have found it preferable to provide the outsidesections with two sets of water-tubes and The intermediate sections withfour sets of water-tubes, as shown in Fig. 3. The intermediate sectionsare provided with steam-space corresponding with the steam-space on theoutside sections and also with openings on each side for connecting withothersections and with openings through the steam-space correspondingwith the iiueescape in the outside sections.

My boiler is especially applicable for use on vehicles, where a greatamount of energy is to be developed quickly and where the weight of theboiler should be reduced ,to a minimum. It will be seen by reference tothe drawings that I accomplish this by having the water-tubes near toand partially surrounding the fire-box I and by means of the water-legsand the Water back and front of ous changes in the form, proportion,andthe l minor details of construction may be resorted l to withoutdeparting from the principle or sacrificing any of the advantages ofthis inventon.

Having thus described myinvention, what l I claim, and desire to secureby Letters Patent, is-

l. In a sectional boiler, sections having water-legs at each side unitedat the top with a Water and steam space of less width than thewater-legs, so as to allow room for the passage of smoke to the topsteam-space where the side parts are brought to other similarconstructedsections, such sections having one or more groups of Water-tubesreaching from the lower part of one leg to the higher part of theopposite leg, groups of waterpipes slanting in opposite directions, allas described.

2. The combination, in a steam-boiler, of a front section provided witha double wall constituting a water-space, a fuel-door and water-tubes atan angle, a rear section provided with a double wall constituting aWater-space, an exit-Hue and water-tu bes placed at an angle,intermediate sections with water-legs and water-tubes placed at an angleand all the sections joined together by pipes or nipples to form acomplete boiler, all as described and for the purposes set forth.

3. The combination, in a steam-boiler, of a front section provided withdouble walls constituting a water-space, a fuel-door and withwater-tubes placed at an angle, a rear section provided with a doublewall constituring a water-space, an exit-flue and watertubes placed atan angle, intermediate sections provided with water-legs, water-tubesplaced at an angle and connecting the legs, an exit-flue extendingthrough the steamre ceptacle of the intermediate section and connectin gwith flue-spaces in the other sections and all the sections joinedtogether by nipples to form a complete boiler, all substantially asdescribed and for the purposes set forth.

4. A steam-boiler comprising independent sections joined together andeach composed of water-legs, and water-tubes connecting said legs, andwater connections between the sections, one of the outer sections beingprovided with an exit-fine for carrying otf the products of combustionand all of said sections having flue-sections leading to the exitfineand in communication with the fire-box.

5. A steam-boiler comprising independent sections composed ofwater-legs, water-tubes connecting the legs, and a steam-drum connectingthe water-legs above the tubes, said sections each having a flue for theproducts of combustion which is within the steamdrum and saidiiues beingin communication with each other when the boiler-sections are togetherand each flue communicating with the fire-box, and water connectionsbetween the sections of the boiler.

6. A steam-boiler comprising independent sections composed ofwater-legs, a steamdrum in its upper part in which is located asmoke-flue communicating with the fire-box, and water-tubes connectingthe waterdegs below the drum, said smoke-fines of the sections formingcontinuations of each other and being provided with an exit in one ofthe sections, water and steam connections between the steam-drumsections7 water connections between the water-legs, and caps which coverthe joints where the boiler-sections meet each other.

In testimony whereof l have signed my name to this specification in thepresence of two subscribing witnesses.

ISHAM SEDGWICK.
